The topeplate 7 is substantially rectanguhit in form having a-Fdependingflange:18 at its edges. Usua llyr in applian-ces o f this type twoburners areprovided, and herein II?

This facilitates the assembling of the parts sinceit renders it-unnecessary to hold the nut by means of a tool while thebolt is being turned.

The means thus provided for fastening the end plates to the top platehas been found to be exceedingly effectual, serving rigidly to hold theparts in proper relation.

The means for effecting the interengagement between the front and rearplates and 11, the top plate ,7, and the end plates 9, so as to holdsaid front and rear plates in position between the end plates, will nowbe described,

Projecting from the underside of the top plate near the front and rearthereof is a series of lugs for holding the front and rear plates 10 and11 against lateral movement. -The lugs 25 are staggered so that thealternate lugs bear against opposite sides of the front and rear plateswhen the latter are pressed against the top plate. The vertical ends ofeach front plate 10 or rear plate 11 are wedged between an inwardlyextending flange 26 on each end plate 9 and a curved shoulder 22 formedon the outer side of the lug 22. It will be remembered that the lugs 22project from the end plate 9 and assist in securing the latter to thetop plate 7. Thus, in the present instance, the upper end and thevertical edges of the front and rear plates 10 and 11 are held betweentwo opposed surfaces, an outer surface formed by the flange 26 and theoutermost lugs 25, and an inner surface formed by the innermost lugs 25and the shoulder 22.

The lower edge of the front plate is supported in sockets 27 formed uponthe inner sides of the end plates 9 as continuations of the flanges 26(Fig. 3) and the lower edges of'the rear plate 11 are supported uponhorizontal ledges 28 and between vertical flanges 29 on said ledges andthe flange 26, said ledges and flanges being formed upon the inner sideof each of the plates 9. Preferably the front and rear plates areconstructed of sheet metal of relatively light guage, the lower edge ofthe front plate being beaded so as to enclose a reinforcing rod 10*, andthe lower edge of the rear plate being provided with an inturned flange30 adapted to engage in the socket provided by the ledges 28 and theflanges 26 and 29.

To receive the drip pan 12 the front plate 10 terminates at shortdistance above the lower edges of the end plates 9, and the latter areprovided at a spaced interval below the sockets 27 with horizontalledges 31 forming supports upon which the drip pan may slide. The flange29 atthe rear edges of the plates 9 constitutes stops for limiting therearward or inward movement 0f the drip pan (Fig. 3). For supporting theappliance in slightly elevated position, the end plates are providedwith feet 32 formed integral therewith.

The gas burners 13 may be of any suitable or preferred construction,adapted to engage with the supporting rod 141-. The opposite ends of thelatter are entered in sockets 33 formed upon the inner sides of the endplates a short distance below their centers.

The gas manifold 15 is in the form of a pipe closed at one end and openat its opposite end so as to be adapted for connection with a suitablesource of gas supply. The brackets-16 for supporting this pipe may be ofany preferred construction, being herein shown as formed of sheet metaland sesured at their upper rear ends to the underside of the top platenear its forward edge.

To this end each of said brackets is provided In order to receive theforward end por- 7 tion of the burner 13, and also provide for theadmission of air to the burner chamber, the front plate 10 is providedwith apertures 37.

It will be observed that-the construction which I have provided isextremely simple,

enabling the construction of the parts at a relatively low cost as wellas their rapid assembling. By the provision of a chamber or housing forthe burners, the efliciency of the appliance 15 increased through thecon-.

centration of the heat upon the cooking utensils supported upon thegrids. over, the enclosed chamber for the burners renders it possible touse the hot plate outof-doors where the ordinary construction isincapable of use because of excessive drafts. Finally, the appearance ofthe appliance is improved by reason of the fact that the housing servesto conceal the unsightly burners from view.

I claim as my invention:

1. A hot plate comprising a rigid top frame provided with one or moregrid openings, a pair of rigid. end plates, means for detachablysecuring the end plates to the under side of the top plate at oppositeends of the latter, said end plates constituting cured t0 the top plate,said rear plate and More-- the two end plates coacting with the topplate to provide a burner chamber.

2. A hot plate comprising, in combination, a rigid top frame providedwith one or more grid openings, a pair of rigid end frames bolted to theunder side of the top frame at opposite ends thereof and constitutingsupports for the top frame, and front and rear plates interposed betweensaid end frames beneath the top frame and interengaging with said framesso as to be held in position by the end frames when the latter aresecured to the top frame.

3. A hot plate comprising, in combination, a rigid top frame providedwith one or more grid openings, a pair of rigid end frames bolted to theunder side of the top frame at opposite ends thereof and constitutingsupports for the top frame, front and rear plates interposed betweensaid end frames beneath the top frame and interengaging with said framesso as to be held in position by the end frames when the latter aresecured to the top frame, and a drip pan supported at its opposite endsby said end frames for sliding movement in a front to rear direction,the front plate having its lower end terminating above said drip pan topermit such sliding movement of the latter.

In testimony whereof, I have hereunto afiixed my signature.
